Verifying a Mapping Tool for Sharing Clinical Data

Abstract

 In Japanese hospitals, it is considerable to research sharing clinical data among multiple institutions. But, hospitals may use respectively their own code on database format so it is difficult for sharing and integrating them. So we tried to use a mapping tool(TMS) for disease codes converting the hospital-oriented code to the common code(ICD-10). Then we developed a mock-up system to be referred by common disease code from another institutions in HOSPnet environment. We verified this system between National Center for Child Health and Development(NCCHD) and National Hospital Organization Mie Chuo Medical Center.
 Consequently, we have realized 95% agreement of disease codes between two institutions, on the condition taking of miss-matching codes between hospital-oriented code and the common code. Also, through network connection with HOSPnet, we can research each hospital data to find, refer, collect and analyze. Besides, it is necessary for us to consider miss matching disease codes, mapping rate of the tool itself, security guidelines and data transfer method via secure and effective network.
